The speed of a wave (c) is the product of its frequency (ν) and wavelength (λ). Correct Answer: E = hv = h x c / λ nm to m or m to nm Correct Answer: 1 m / 10^9 nm or 10^9 nm / 1 m What is the maximum number of electrons that can have the quantum numbers n = 3, ℓ = 2, mℓ = -2? Correct Answer: The Pauli exclusion principle states that no two electrons in a given atom can share the same set of four quantum numbers (n, ℓ, mℓ, ms). This set of quantum numbers contains three...

Introduction to Quantum Mechanics Graded A+ Back to Bohr: Bohr gave us Quantization Quantization means electrons can only exist in certain discrete energy levels (like a staircase, they can only completely be on the first or second stair but never in between stairs different distances from ground) If you recall rings= orbits e- must be in a _______ and e- are different distances(or E) from ________ orbit; nucleus Bohr was Bad: Bohr model of the atom could predict the ____________ _...

Rutherford's Gold Foil Experiment - proposed that atoms consist of a tiny, massive, positive nucleus surrounded by electrons nucleus - contains all the positive charge and nearly all the mass of the atom James Chadwick - discovered the neutron cathode rays - move from negative electrode to positive electrode (like electrons in a voltaic cell) Thompson's Cathode Ray Experiment - discovery of the electron (also the discovery that atoms are divisible into smaller particles) Milliki...

Chem 219: Exam Questions With 100% Correct Answers The speed of a wave (c) is the product of its frequency (ν) and wavelength (λ).

BCH 463: BIOPHYSICAL CHEMISTRY FINAL EXAM 2024 WITH 100% ACCURATE SOLUTIONS What is the "average energy" in the equation that Planck used to fix the Rayleigh-Jean classical prediction on blackbody radiation? (A) hν/(e^(hν/(k_B T))-1) (B) 8πν/c^3 (C) k_B T (D) nhv - correct answer (A) hν/(e^(hν/(k_B T))-1) As seen in the image, if the 8π^3/c^3 terms are ignored, the simplified expression is the answer. The following figure shows the measurement of the energy density emitte...

Quantum Mechanics Already Graded A+ Max Planck : German physicist who solved the problem of why different wave lengths are emitted at different temperatures- proposed that the energy absorbed or emitted by an object could only occur in "pieces"- which he called quantum Wener Heisenberg : German theoretical physicist- published his theory on quantum mechanics when he was 23- concluded that it is impossible to make a measurement on an object without disturbing the object Albert...

Atomic Number - correct answer number of protons found in that atom; low number; (Z) Mass Number - correct answer Protons + Neutrons; high number; (A) Atomic Mass - correct answer relative mass of that atom compared to the mass of a carbon-12 atom (which is set at 12.00); measured in amu; 1 amu = - correct answer 1.66x10^-24 Atomic Weight - correct answer weight (g) of one mole (mol) of a given element (g/mol); the weighted average of all the masses (not the weights) of an element, w...
